The Enigma Strain

Deep within the Amazon rainforest, a secret lurks. A secret that could change the world.

...A secret worth killing for.

When her company discovers a remarkable hidden message in the dreaming brains of her subjects, Dr. Amanda Meron unknowingly invites disaster unto her company. The clues seem to be pointing her to one of the remote places on the planet:

The Amazon Rainforest.

When Harvey "Ben" Bennett gets a hint that the nefarious organization he's been searching for has turned up in Brazil, he and his new girlfriend Juliette Richardson race to the jungle to discover what they're after — and hopefully stop them.

From the myth of the lost city of El Dorado to emerging science technology, The Amazon Code has it all: action-packed adventure, an exotic setting, and characters you'll fall in love with.

A door in the ice is discovered in the middle of nowhere in Antarctica.

Worst of all, an army of Chinese soldiers — hoping to get their hands on the tech — are at their heels. 

The Ice Chasm is the third installment of the fast-paced sci-fi thriller that will have you clinging to the edge of your seat. It is a nonstop, action-packed technothriller about artificial intelligence, the unending push toward scientific discovery, corporate conspiracies, and the human condition.

The Ice Chasm

He was murdered for a secret — one he took to his grave.

200 years later, that secret is haunting him again.

Meriwether Lewis was murdered. The organization behind it has been growing quietly in the shadows. 

And only Harvey Bennett and the CSO can stop them.

Harvey “Ben” Bennett is back, and he’s not alone. His new team — the Civilian Special Operations — is putting the finishing touches on their new headquarters when they receive a call: There’s been a murder. And in its wake, a seemingly insignificant artifact has been stolen. 

Ben and company make their way to Philadelphia to investigate the death and are greeted by a modern-day American Philosophical Society —and learn that they are protecting a deadly secret that reaches back through history to Founding Fathers themselves.

What was the secret that Meriwether Lewis died for? 

And why are so many willing to kill for it today?

From the author that brought you the bestselling The Enigma Strain, comes The Jefferson Legacy, the latest installment of the edge-of-your-seat series, the Harvey Bennett Thrillers.
